Under iron-limiting conditions, Pseudomonas aeruginosa secretes a fluorescent siderophore called pyoverdin (PaA), which, after complexing iron, is transported back into the cells via its outer membrane receptor FpvA. The recent finding that all FpvA receptors on the bacterial cell surface are loaded with iron-free PaA under iron limiting conditions has

Chemistry and Biology of Pyoverdines, Pseudomonas Primary Siderophores
Current Medicinal Chemistry, 2014Pyoverdine is the generic name given to a vast family of fluorescent green-yellowish pigments produced by Pseudomonas species. Pseudomonas aeruginosa is an opportunistic pathogen, particularly infecting humans with compromised natural defenses. These infections result in significantly higher morbidity, longer hospitalization, increased mortality rates ...

Formation of the Chromophore of the Pyoverdine Siderophores by an Oxidative Cascade
Organic Letters, 2003The pyoverdine chromophore is formed in a reaction involving a two-electron oxidation, a conjugate addition, and a second two-electron oxidation. This oxidative cascade can be carried out with polyphenol oxidase (PPO), MnO(2), and cell-free extracts from Pseudomonas aeruginosa. [reaction: see text]

From Pseudomonas sp. CFML 96.188 a pyoverdine was isolated and its primary structure was elucidated by spectroscopic methods and degradation reactions. This strain is of interest as it accepts the structurally different pyoverdines from several other Pseudomonas strains.

Two Pseudomonas fluorescens and one Pseudomonas aeruginosa strains, although producing structurally different pyoverdines, demonstrated highly efficient cross-reactions when tested for pyoverdine-mediated iron uptake. A ferripyoverdine receptor-deficient mutant of the P. aeruginosa strain was unable to use any of the three pyoverdines.

Exploring the sociobiology of pyoverdin-producing Pseudomonas.
Evolution; international journal of organic evolution, 2013The idea that bacteria are social is a popular concept with implications for understanding the ecology and evolution of microbes. The view arises predominately from reasoning regarding extracellular products, which, it has been argued, can be considered "public goods." Among the best studied is pyoverdin-a diffusible iron-chelating agent produced by ...

From a genetically manipulated strain of Pseudomonas aeruginosa ATCC 15692 (PAO1 strain) a compound named pseudoverdin, 3-formylamino-6,7-dihydroxycoumarin, was obtained which is related to the typical pyoverdin chromophore and thus allows to shed some light on the biogenesis of the latter.
